In PHP, how do I search arrays for production systems?

In PHP, you can search arrays using various methods such as `in_array()` and `array_search()`. These functions are essential for production systems when you need to check for the existence of a value or its key within an array.

Description: This guide illustrates how to efficiently search arrays in PHP, a crucial task in production environments to maintain data integrity and performance.
<?php // Example array $productionSystems = ['System A', 'System B', 'System C']; // Search for a value if (in_array('System B', $productionSystems)) { echo "System B is in the list of production systems."; } else { echo "System B is NOT in the list of production systems."; } // Search for a key $key = array_search('System A', $productionSystems); if ($key !== false) { echo "Found System A at index: " . $key; } else { echo "System A not found."; } ?>
